AMD RX 7900 XTX vs NVIDIA RTX 4080 Super

Launch MSRPs, release cycles and deals windows as of November 9, 2026.

This is a cross-brand comparison between the AMD RX 7900 XTX (RX 7000, Enthusiast, superseded by the AMD RX 9070 XT) and the NVIDIA RTX 4080 Super (RTX 4000, Enthusiast, superseded by the NVIDIA RTX 5080), released 13 months apart. Against the RTX 4080 Super, the RX 7900 XTX launched at the same $999 MSRP, has 8 GB more VRAM (24 GB vs 16 GB) and draws 35W more at rated TDP (355W vs 320W).

Cross-brand comparison: NVIDIA offers DLSS and CUDA for AI/ML workloads. AMD offers competitive rasterization, often with more VRAM at the same price. Choose based on your ecosystem needs.

Why buy each?

AMD RX 7900 XTX

24GB GDDR6 — massive VRAM

More VRAM than any RTX 5000 card except the 5090. Unmatched for VRAM-hungry workloads.

FSR 4.1 upscaling support

Adrenalin 26.6.2 (June 2026) brought official FSR 4.1 ML upscaling to RDNA 3 in 300+ games — a clear image-quality step up from FSR 3.1.

Mature RDNA 3 drivers

Over 3 years of driver optimization, with Adrenalin 26.6.4 fixing early FSR 4.1 issues on RDNA 3.

NVIDIA RTX 4080 Super

Used market value

New units sell around $1,400–$1,600 and used units start around $1,100 as of October 2026 — both above the $999 MSRP. Only worth it if a used unit turns up well below MSRP.

16GB GDDR6X

Ample VRAM for 4K gaming and content creation.

Mature Ada Lovelace drivers

Over 2 years of optimizations ensures stability across all titles.

Timing: When to Buy

Released Dec 13, 2022, the RX 7900 XTX has been on the market for 3 years 10 months. It has been superseded by the AMD RX 9070 XT, which launched Mar 6, 2025, so it's no longer a current-generation buy — new stock is clearance, and the rest of the market is second-hand.

Released Jan 31, 2024, the RTX 4080 Super has been on the market for 2 years 9 months. It has been superseded by the NVIDIA RTX 5080, which launched Jan 30, 2025, so it's no longer a current-generation buy — new stock is clearance, and the rest of the market is second-hand.

Both cards are superseded. If you're buying new, their replacements — the AMD RX 9070 XT and NVIDIA RTX 5080 — are where current pricing and timing advice apply.

Deals & Pricing

Both cards launched at $999, so at MSRP the decision comes down to what that money buys. Per gigabyte of VRAM that's $41.6 for the RX 7900 XTX and $62.4 for the RTX 4080 Super — the RX 7900 XTX gives more memory for the money. Launch MSRP is only a reference point for a superseded card; its real price is whatever clearance or used stock sells for today.

RX 7900 XTX (deals window to Dec 5, 2026, rated Caution): Black Friday 2026 — analysts do not expect memory supply to normalise before late 2027, so real clearance pricing is unlikely. Only buy if a deal lands below the $999 MSRP.

RTX 4080 Super (deals window to Jun 30, 2027, rated Wait): No clearance — new retail prices are ~40–60% above $999 MSRP due to production ending and scarcity, and used units start around $1,100 as of October 2026. Only consider a used unit well below MSRP.

Who Should Choose Each

Choose the AMD RX 7900 XTX if…

  • you want more VRAM — 24 GB vs 16 GB
  • you prefer AMD's FSR3 upscaling to NVIDIA's DLSS3
  • you find one on clearance or second-hand for clearly less than the RTX 4080 Super costs

Choose the NVIDIA RTX 4080 Super if…

  • you want lower power draw — 320W vs 355W rated TDP
  • you want newer GDDR6X memory rather than GDDR6
  • you want the newer card — it launched 13 months later
  • you prefer NVIDIA's DLSS3 upscaling to AMD's FSR3
  • you find one on clearance or second-hand for clearly less than the RX 7900 XTX costs

Our Take

Both of these cards are superseded, so if you're buying new, compare the AMD RX 9070 XT and NVIDIA RTX 5080 instead. The rest of this verdict applies to clearance or used units.

On our data this one is a genuine toss-up: editor scores, buy/wait timing and launch price are all level. Let the price on the day — and the upscaler ecosystem you prefer — decide.
